I am having an issue using BackTrack 5 r3 on VMware on my Acer laptop.
Equipment used:
Acer Aspire 5560-7402 with Windows 7 Home Premium Sp1 64 bit.
VMware Work Station 8.0.5 build-893925
TP-Link TL-WN722N wireless antenna.
I can connect to the internet with the antenna. And I have run #wash -i mon0 -C and I know that the routers are vulnerable. When I run Reaver on any wireless router that i own I get the same error code over and over again.

Any ideas?
